So I decided that I am only going to have 1 tv connected to satellite, and therefore bought an indoor antenna (flat window type). Upon connection, I am able to get the following channels (4.1, 6.1, 11.1, 14.1, 24.1, 30.1, 40.1, 42.1, 43.1, 60.1, 65.1). However, the channel i want the most is 13.1. Any advice on how to get this? The antenna is facing East and is on the main floor window with minimal obstruction.

Facing the flat antenna towards the east should give you most of the channels to the southeast (those at 136 degrees). Channel 13.1 (CTV) is with the group of stations to the north (at 350 degrees), meaning that your east-facing flat antenna is trying to pick it up from the side (which is difficult). I recommend experimenting. Try facing your antenna towards the south-southeast (which is also the north-northwest since it is a flat panel). Also try it at different points in the room and at different heights.
